ABSTRACT
BackgroundKidney transplant patients due to both primary kidney involvement of chronic/autoimmune inflammatory diseases and end-stage kidney disease related to amyloidosis are followed up in rheumatology clinics. Biological agents one of the treatment options in kidney transplant recipients with chronic/autoimmune inflammatory disease.ObjectivesHowever, there is insufficient data on the development of infection in kidney transplant recipients who received biological treatment. Herein, we aimed to determine the incidence of serious infections in patients with kidney transplant recipients who are received biological therapy.MethodsKidney transplant recipients who are received biological agents due to rheumatologic disease were included in the study. Patients' demographic features, transplantation data, biological treatment, development of infection and severity of infection were screened retrospectively. Infections that requiring hospitalization were defined as severe infections.ResultsA total of 31 patients were included in the study, 14 (45%) of whom were female and mean age was 41 ±9 years. Twenty-five patients (80%) of them were non-preemptive kidney transplant and mean duration of hemodialysis before the transplantation was 40 ±40 months. Twenty-three patients (74%) had end stage kidney failure due to FMF-amyloidosis(Figure-1-). Seventeen patients (54%) received anakinra, 11 patients (35%) received canakinumab and 3 patients (10%) received etanercept with other immunosuppressive treatment. Mean treatment duration of biological agents was 4.2±2.6 years. Two patients developed solid organ malignancy and one patient developed hematological malignancy after transplantation. Sixteen of the patients (52%) were hospitalized at least once due to infection and 4 patients (13%) died due to infection. The cause of decease in two patients was COVID-19.ConclusionRheumatic diseases are an important cause of end-stage renal disease and definitive treatment is kidney transplantation. Kidney transplant recipients due to rheumatological disease also use biological agents in the post-transplantation period. Kidney transplant recipients have higher risk for the development of infection since they receive immunosuppressive therapy and use of biologic agents may further increase the risk for development infection. Meyer et al reported that infection developed in 54 of 187 solid organ transplant recipients using biological agents.[1] Mean treatment duration of biological agents was 12 months in this study. The incidence of infection was 54% in our study. Mean treatment duration of biological agent was 4.2 year was considered main reason for higher incidence of infection in our study.Reference[1]Meyer F, Weil-Verhoeven D, Prati C, Wendling D, Verhoeven F.

ABSTRACT
Purpose: To evaluate the relationship between the presence of kidney stones and COVID-19. Materials and methods: Patients, who were treated for COVID-19 as outpatients as well as inpatients in the ward and/or ICU of two different secondary and tertiary care centers between July 15, 2020, and December 31, 2020, and aged ≥18 years were retrospectively evaluated. The patients were divided into two subgroups based on the presence of kidney stones, and then the patients with kidney stone were categorized into three groups: those who were treated in an outpatient setting (Group 1), those who were treated in the ward (Group 2), and those who were treated in the intensive care unit (Group 3). Results: The total of 1,335 COVID-19 patients included in the study. Kidney stone was present in 31 (6.9%) of 450 outpatients, 41 (8.9%) of 460 inpatients treated in the ward, and 60 (14.1%) of 425 inpatients treated in the intensive care unit. In Group 1, the duration of COVID-19 treatment was significantly longer in patients with kidney stone than patients without kidney stone (8.1±1.7 vs. 6.8±2.2 days, p=0.01). In Group 2 and in Group 3, the mean hospitalization duration was significantly longer in patients with kidney stone than in those without kidney stone (9.1±3.7 vs. 6.2±2.1 days, p=0.007;19.1±8.1 vs. 11.3±6.2 days, p=0.001, respectively). Conclusion: The duration of COVID-19 treatment was longer and the COVID-19 infection was more severe in those with kidney stones. © 2022, Pamukkale University. All rights reserved.
ABSTRACT
Objective Closing of schools within the scope of the pandemic measures and switching to online education have negatively affected the mental and physical health of children as well as their education. The effect of complete reopening of schools on the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not fully known. In the 2021-2022 academic year, the Ministry of National Education of Turkiye has decided to continue face-to-face education at all levels and in all private and public schools, by following a series of measures. There are no studies on school transmission reported from Turkiye since then. This study aimed to assess the dynamics of coronavirus diseases 2019 (COVID-19) transmission in schools by evaluating the data of the school contact screening outpatient clinic of a tertiary children's hospital. Methods According to the Ministry of National Education guidelines in Turkiye, all students in a class with two polymerase chain reaction (PCR)-confirmed COVID-19 cases are sent to their homes and have a SARS-CoV-2 PCR test on the fifth day. While the students with negative test results return to school, students who test positive continue to stay at home until the 10th day. The current study retrospectively analyzed the screening results of primary, middle, and high school students who presented at the school contact screening polyclinic during the first semester of the 2021-2022 academic season. Discussion There were a total of 11,608 presentations to the school contact screening polyclinic, and 1,107 children tested positive with SARS-CoV-2 PCR (9.5%). The median weekly positivity rate was 9.7% in primary school, 9.4% in middle school, and 5.6% in high school. The weekly positivity rate increased from the 16th week at all school levels;the positivity rates ran in parallel before this time but significantly increased from the 16th week to the half-term break. Conclusion The curve of the positivity rates in schools was similar to Turkiye's pandemic curve. In this respect, the low SARS-CoV-2 transmission in schools correlated with the low number of cases in the community.
